With Republican-backed voting bills moving rapidly through a special session of the state Legislature, Texas Democrats are planning to make a break for it — again.At least 58 Democratic members of the state House of Representatives are expected to bolt from Austin on Monday in an effort to block the measures from advancing, a source familiar with the plans told NBC News. The unusual move, akin to what Democrats did in 2003, would paralyze the chamber, stopping business until the lawmakers return to town or the session ends.
